Species Richness and the Analytic Geometry of Latitudinal and Altitudinal Gradients

Acta Biotheoretica, 2008
Extensive empirical work has shown that species richness decreases roughly exponentially or quadratically with latitude. What appears to be a latitudinal gradient in fact may simply be a negative correlation of latitude with area at that latitude, due to convergence of lines of meridian at the poles.

Altitudinal Gradients in Mycorrhizal Symbioses

2017
Mountains, due to their often steep gradients in abiotic and biotic factors, offer an ideal setting to improve our understanding of mechanisms that underlie species distribution and community assembly. The current knowledge on the effects of elevation on richness and community composition is almost entirely based on vascular plants and animals, where ...

[Heat transfer, convection and altitudinal gradient].

Archivos de biologia y medicina experimentales, 1996
Measurements of heat loss from fur covered aluminium cylinders were made under barometric pressures ranging from 760 to 368 torr (sea level up to 5.8 km, simulated altitudes). Heat transfer diminished at high altitudes and a relative greater diminution was observed when forced convection was applied.

Altitudinal gradients fail to predict fungal symbiont responses to warming

Ecology, 2019
AbstractClimate change is shifting altitudinal species ranges, with potential to disrupt species interactions. Altitudinal gradient studies and warming experiments can both increase understanding of climate effects on species interactions, but few studies have used both together to improve predictions.

Stomatal Frequency Change Over Altitudinal Gradients: Prospects for Paleoaltimetry

Reviews in Mineralogy and Geochemistry, 2007
Recently, a novel paleoaltimetry method was presented using leaf stomatal frequency response to the decline in CO 2 partial pressure with altitude, and tested on California black oak ( Quercus kelloggii ) (McElwain 2004). Here, we present new data detailing the influence of other climatic variables on leaf stomatal frequency change with altitude in ...

Diversity of Tricholomataceae along a mediterranean altitudinal gradient

Cryptogamie Mycologie, 2001
Abstract This work studies variability in the composition of Tricholomataceae in different types of forest along an altitudinal gradient in the province of Madrid. It gives 26 new regional references, including most importantly Collybia aquosa, Clitocybe collina, Melanoleuca metrodiana, Cantharellula umbonata, Clitocybe decembris, Clitocybe ...
